[0038] like Figure 1-7 As shown, this embodiment provides a lifting type side sliding sealed door structure, including a door frame 1, a door body 4, a sealing assembly, a door opening mechanism, a tensioning mechanism and a lifting mechanism.

[0039] The door frame 1 is welded from high-strength structural steel, has good strength and structural rigidity, is not prone to deformation, and is provided with a door hole.

[0040] The door body 4 is machined from high-strength structural steel, has good strength and structural rigidity, and is not prone to deformation. The door body 4 is used to block or open the door hole of the door frame 1.

[0041] The door opening mechanism includes a lower mounting plate 5, an upper mounting plate 7, a guide rail assembly and a slide rail assembly. The upper mounting plate 7 and the lower mounting plate 5 are respectively arranged on the upper and lower sides of the door body 4, and the bottom of the upper mounting plate 7 is pivotally connected to the door frame 1 through a door shaft 14. The lower mounting plate 5 and the upper mounting plate 7 are machined from high-strength structural steel, have good structural rigidity, and are not easily deformed. The guide rail assembly is provided with two sets and is symmetrically arranged on the left and right sides of the door body 4 (also located on the front side of the door frame 1), and each set of guide rail assemblies includes a guide rail 2 and a linear bearing 3, which ensures the stability of the door body when sliding sideways; the guide rail 2 is fixed between the lower mounting plate 5 and the upper mounting plate 7; there is at least one linear bearing 3 (at least one linear bearing 3 is arranged on the guide rail 2 of each set of guide rail assemblies), and the linear bearing 3 is installed on the corresponding side of the door body 4 (at least one linear bearing 3 is installed on the left and right sides of the door body 4 respectively), and the linear bearing 3 is also installed in cooperation with the guide rail 2 and can make a linear motion along the guide rail 2 (and can also be lifted and lowered with the guide rail 2); the guide rail 2, the upper mounting plate 7 and the lower mounting plate 5 are connected by screws to form a stable frame structure. The slide rail assembly includes a slide rail 11, a slider 12 and a motor 13; the motor 13 is fixedly mounted on the lower mounting plate 5 by screws; the slide rail 11 is a screw structure with an external thread on the outer side, and couplings 10 are respectively connected to both ends of the slide rail 11, one end of which is rotatably mounted on the upper mounting plate 5 through a support shaft 8 (the support shaft 8 is mounted on the upper mounting plate 7 through a bearing 9 and is coaxially connected to the slide rail 11 through a coupling 10), and the other end is coaxially connected to the rotating shaft of the motor 13 through another coupling 10; the slider 12 is sleeved outside the slide rail 11 and threadedly matched with the slide rail 11 (the slider 12 and the slide rail 11 constitute a screw substructure), and the slider 12 is also fixedly connected to the door body 4 by screws. When the motor 13 drives the slide rail 11 to rotate, the slider 12 (driven by the slide rail 11) drives the door body 4 to make a linear motion along the slide rail 11. The slide rail assembly is driven by the motor 13, which can ensure that the door body 4 slides smoothly and accurately slides to the required sliding position.

[0042] The sealing assembly is arranged between the door frame 1 and the door body 4 to achieve sealing between the door frame 1 and the door body 4; Figure 4 As shown, the sealing assembly includes a sealing ring 17 and a sealing ring slot 18; the sealing ring slot 18 is fixed to the door frame 1 by welding and corresponds to the inner position of the door body 4; the sealing ring 17 is bonded in the sealing ring slot 18 using quick-drying glue.

[0043] The tensioning mechanism is at least one set and is arranged between the lower mounting plate 5 and the door frame 1, and is used to tighten the door body 4 on the door frame 1; in order to make the door body 4 tightly tightened on the door frame 1, an effective seal between the door body 4 and the door frame 1 is achieved, such as Figure 5As shown, each set of tensioning mechanism includes a sealing tension spring 16 and two tension spring seats 15 respectively fixed at both ends of the sealing tension spring 16. The two tension spring seats 15 are respectively fixed to the lower mounting plate 5 and the door frame 1 by screws. The sealing tension spring 16 tensions the door body 4, and the door body 4 compresses the sealing ring 18 to deform, thereby eliminating the gap between the door body 4 and the sealing ring slot 18 to form a sealing structure. The spring force of the sealing tension spring 16 is used to press the door body 4, forcing the sealing ring 17 to deform, thereby ensuring the sealing performance between the door body 4 and the door frame 1.

[0044] The lifting mechanism is arranged at the rear side of the lower mounting plate 5, and is used to lift the door body 4 by lifting the lower mounting plate 5 when the door is opened (that is, first by lifting the frame structure formed by the guide rail 2, the upper mounting plate 7 and the lower mounting plate 5, and then the frame structure synchronously drives the slide rail assembly and the linear bearing 3 to move upward, and then drives the door body 4 connected to the slider 12 and the linear bearing 3 to move upward). The lifting mechanism is a set of mechanical mechanisms, which uses gas as an actuating energy source and can realize the lifting and lowering of the door body 4. After the door body 4 is lifted, the sealing ring 17 and the door body 4 are completely separated, eliminating the friction between the door body 4 and the sealing ring 17 during the side sliding process, reducing the door opening resistance, and extending the service life of the sealing ring 17. In order to ensure the smooth lifting and lowering of the door body 4 when opening the door, reduce the door opening resistance, and avoid the wear, deformation, and falling off of the sealing ring 17, as shown in FIG. Figure 6 and Figure 7As shown, the lifting mechanism includes a base plate 19, a mounting plate 20, a fixed shaft 21, a left connecting rod 22, a right connecting rod 23, a roller 24, a rotating shaft 25, a sliding shaft 26, a cylinder joint 27, a recovery tension spring 28 and a cylinder 29; the base plate 19 is welded and fixed to the door frame 1 and is located at the rear side of the lower mounting plate 5; the mounting plate 20 is fixed to the base plate 19 by screws (laterally), and an oblong hole 201 is provided on the mounting plate 20 along its length direction; the fixed shaft 21 is rotatably mounted on the mounting plate 20 and is located at the left end of the mounting plate 20; the sliding shaft 26 is rotatably mounted in the oblong hole 201 of the mounting plate 20 and can make a linear motion along the oblong hole 201, and the sliding shaft 26 is located at the right end of the mounting plate 20; the rotating shaft 25 is arranged between the fixed shaft 21 and the sliding shaft 26 and is located at the front side of the mounting plate 20 (not The roller 24 is rotatably mounted on the rotating shaft 25 and its wheel surface is pressed against the rear side of the lower mounting plate 5; the two ends of the left connecting rod 22 are rotatably mounted on the fixed shaft 21 and the rotating shaft 25 respectively; the two ends of the right connecting rod 23 are rotatably mounted on the rotating shaft 25 and the sliding shaft 26 respectively; the cylinder 29 is fixedly mounted on the bottom plate 19 by screws and its telescopic end faces the sliding shaft 26 and is located on the right side of the mounting plate 20; the two ends of the cylinder joint 27 are respectively connected to the sliding shaft 26 and the telescopic end of the cylinder 29, and the left end of the cylinder joint 27 is sleeved on the sliding shaft 26 and has an interference fit with the sliding shaft 26; the recovery tension spring 28 is arranged between the sliding shaft 26 and the cylinder 29, and its two ends are respectively connected to the mounting plate 20 and the sliding shaft 26.

[0045] The door opening process is as follows:

[0046] like Figure 6 and Figure 7 As shown, the air cylinder 29 is activated by air intake, pushing the sliding shaft 26 to overcome the spring force of the recovery tension spring 28 and move to the left (in the figure) in the oblong hole 201 of the mounting plate 20, and the right connecting rod 23 performs a combined motion of a left linear motion and a clockwise rotation around the sliding shaft 26, and the left connecting rod 22 rotates counterclockwise around the fixed shaft 21. The roller 24 performs an upward linear motion, and the roller 24 lifts up the lower mounting plate 5. The lower mounting plate 5 overcomes the spring force of the sealing tension spring 16 and rotates around the door shaft 14, driving the door body 4 to separate from the sealing ring 17. When the air cylinder 29 reaches the stroke position, the roller 24 lifts up the lower mounting plate 5 to the highest position, at which time the door body 4 is completely separated from the sealing ring 17; after the door body 4 is completely separated from the sealing ring 17, as shown in FIG. Figure 2 As shown, the motor 13 drives the slide rail 11 to rotate clockwise, and the slider 12 drives the door body 4 to move upward. At the same time, the linear bearing 3 moves upward along the guide rail 2 to guide. The size of the door opening is precisely controlled by the motor 13. When the door body 4 reaches the desired position, Figure 6 and Figure 7As shown, the cylinder 29 releases pressure, the sliding shaft 26 moves to the right (in the figure) under the action of the spring force of the recovery tension spring 28, the roller 24 moves downward, and after the lower mounting plate 5 loses the pressure of the roller 24, the door body 4 presses the sealing ring 17 under the action of the sealing tension spring 16 to complete the door opening action.

[0047] The closing process is as follows:

[0048] like Figure 6 and Figure 7 As shown, the air cylinder 29 is activated by air intake, pushing the sliding shaft 26 to overcome the spring force of the recovery tension spring 28 and move to the left (in the figure) in the oblong hole 201 of the lifting mechanism mounting plate 20, and the right connecting rod 23 performs a combined motion of linear motion to the left and clockwise rotation around the sliding shaft 26, and the front connecting rod 22 rotates counterclockwise around the fixed shaft 21. The roller 24 performs an upward linear motion, and the roller 24 lifts the lower mounting plate 5. The lower mounting plate 5 overcomes the spring force of the sealing tension spring 16 and rotates around the door shaft 14, driving the door body 4 to separate from the sealing ring 17. When the air cylinder 29 reaches the stroke position, the roller 24 lifts the lower mounting plate 5 to the highest position. At this time, the door body 4 is completely separated from the sealing ring 17; after the door body 4 is completely separated from the sealing ring 17, as shown in FIG. Figure 2 As shown, the motor 13 drives the slide rail 11 to rotate counterclockwise, and the slider 12 drives the door body 4 to move downward. At the same time, the linear bearing 3 moves downward along the guide rail 2 to guide. Figure 6 and Figure 7 As shown, the cylinder 29 releases pressure, the sliding shaft 26 moves to the right (in the figure) under the action of the spring force of the recovery tension spring 28, the roller 24 moves downward, and after the lower mounting plate 5 loses the pressure of the roller 24, the door body 4 presses the sealing ring 17 under the action of the sealing tension spring 16 to complete the door closing action.
